The purple red encrusting of my starburst polyps seems to be thining out. This encrusting used to be pretty thick and wraps round a piece of LR. But in recent weeks, it is thinning out and there are a few holes appearing through it, so you can see the rock surface underneath it. Some of the polyps on this thinned out encrusting also seems to have died.
What is the problem here? However, the encrusting is still growing and spreading across other part of the LR.
